Here are the two floatplanes I see the most around the airport.
I keep forgetting what the big guy is in the first picture. He seems to get someone to pay for the gas once or twice a weekend each month. I love the sound of it's two big radials though, not quite as nice as the resident B-25's roar, but the closest to it. (only pic I have at the moment, I
think I have a better one hiding somewhere...)

(other planes pictures from L to R - SpitXIV, P51D, and F8F)
The second one I have no clue about and see a lot less often about the airport, but I have seen it a half-dozen times.

Also have a bunch of photos and a short clip with my camera of a Lockheed Constellation that tookoff outa the airport in January to live and get restored in Chino I think, really big and unique looking bird. Also got a bunch of other photos not-related to the topic to share.
